"By doing this, we've been able to adjust the finish screen and give them 10-15 percent more production of that ¼-in.-minus material that was being produced by the crush- ers but not being pulled out by the screens." "We like to look at the screens as the cash register, where you tally up at the end of the day how much material you actually made, and in order to do that, we have to adjust the screens accordingly," he added. Henrie selected the Kodiak Plus cone crushing product line because of its ability to succeed in all applications, he said. Here, he runs the K400+ cone crusher in a tertiary appli- cation at 950 rpm with an extra fine liner, and the K400+ cone crusher in a secondary application at 900 rpm with a medium fine liner, which enables Henrie to produce the maximum amount of ¼-in.-minus material. Stopping Tramp Iron The hydraulic tramp iron relief system on the Kodiak Plus Cone Crushers also proves beneficial in ore crushing ap- plications, as the crusher is forced to process a variety of uncrushable material such as drill pieces. The Kodiak Plus cone crushing products utilize a unique, patented tramp iron pressure relief system that protects the machine from tramp iron events and eliminates the maintenance costs and violent back pressure associated with accumulators. The product line also features a precision roller bearing design as well as a new hybrid cast/fabricated base frame design, the "MILO" automated control system, a new patent- ed liner retention system, patented thread locking ring and anti-spin cone brake. "These cones, they can handle whatever we throw at it," Harrison said. "The hydraulic mechanism works well, and it allows for a long bearing life and a long crusher life because of it." Like any machine, the equipment can only function as well as the operator, and Harrison said Henrie is diligent in both balancing the plant and maintaining his equipment, which is critical to his success. "Gene does an excellent job in making sure both cone crush- ers are choke fed, which is all you can ask for in these kinds of applications," Harrison said. "Because of that, he's able to sustain a high average for tonnages per hour. He's also fan- tastic at maintaining the equipment and making sure it's up and running every day. As a result of his dedication to main- taining the equipment and constantly ensuring the equip- ment is set up in a way to achieve the best production, he's been able to be tremendously successful in this application."
